How to Control the Quality of Diamond Micron Powder

Synthetic diamond powder is mainly used in precision polishing and grinding of workpiece. Usually the users require the lowest diamond concentration, the fastest cutting speed to obtain the best geometry and surface finish of the workpiece, and the smallest possible of surface micro-damage. Only high-quality diamond powder can meet the requirements of these cases. Therefore the four items below should be strictly controlled.

(1).Size and concentration of Particles.

(2).Particle size distribution.

(3).particles shape

(4).strength of diamond

Among the four items, first two items are particularly important. For example, if there are too much coarse particles, the efficiency of cutting and grinding will be high, but the quality of surface finish will be declined). Conversely, if there is too much fine particles, it will benefit the efficiency of cutting and grinding speed, and lower down the quality of surface finishment.

Particles shape not only influence the quality of surface finishing, but also effect the strength of diamond micron powder.

Test shows that it is suitable to have the particles closed to block-shaped and sharp-edge shape.

The strength of diamond micron powder depends on the quality of raw material, which also directly affect the shape of diamond micron powder after crushing. So the higher quality of raw materials (Synthetic Diamond) is, the higher efficiency and longer lifespan of diamond micron powder will be.
